What is the primary function of the SA C) To initiate electrical impulses that set the rhythm
node in the heart? and rate of the heart; "pacemaker" of the heart
A) To slow down the heart rate
B) To act as a gatekeeper for electrical
signals
C) To initiate electrical impulses that
set the rhythm and rate of the heart;
"pacemaker" of the heart
D) To contract and pump blood to the
ventricles
What is the role of the AV node in the C) To slow the electrical signal before it enters the
cardiac conduction system? ventricles
A) To act as the primary pacemaker of
the heart
B) To contract and pump blood into
the ventricles

What is the term used to describe the B) Preload
filling of the ventricles with blood?
A) Afterload
B) Preload
C) Stroke volume
D) Cardiac output
Afterload refers to: A) The amount of pressure needed to pump blood
out of the ventricles; the resistance the left ventricle
A) The amount of pressure needed to must overcome to pump the blood into circulation
pump blood out of the ventricles; the
resistance the left ventricle must
overcome to pump the blood into
circulation
B) The amount of blood returning to
the heart
C) The volume of blood filling the
ventricles before contraction
D) The electrical impulses that set the
heart rate
Which formula correctly represents C) CO = HR x SV (Stroke Volume)
cardiac output (CO)?
A) CO = HR + SV (Stroke Volume)
B) CO = HR - SV (Stroke Volume)
C) CO = HR x SV (Stroke Volume)
D) CO = HR / SV (Stroke Volume)
,What is the primary difference B) Atherosclerosis involves plaque buildup that
between atherosclerosis and obstructs blood flow, while arteriosclerosis refers to
arteriosclerosis? the hardening of arteries.
A) Atherosclerosis refers to the
hardening of arteries, while
arteriosclerosis involves plaque
buildup.
B) Atherosclerosis involves plaque
buildup that obstructs blood flow,
while arteriosclerosis refers to the
hardening of arteries.
C) Atherosclerosis is a type of
arteriosclerosis that affects the veins,
while arteriosclerosis affects the
arteries.
D) Atherosclerosis results from high
blood pressure, while arteriosclerosis
results from high cholesterol levels.

signs and symptoms of pulses
atherosclerosis?
A) Chest pain, shortness of breath,
high heart rate
B) Fatigue, weakness, pain in legs,
absent/weak pulses
C) Dizziness, nausea, high blood
pressure
D) Palpitations, sweating, high blood
pressure
What happens when the SA node fires C) It leads to a rapid heart rate called tachycardia,
too quickly? where the heart beats faster than normal.
A) It leads to a condition called
bradycardia, where the heart beats
slower than normal.
B) It results in an irregular heart
rhythm known as atrial fibrillation.
C) It leads to a rapid heart rate called
tachycardia, where the heart beats
faster than normal.
D) It causes the heart to stop beating.
